Securing WebAssembly Runtimes with Post-Quantum Algorithms

WebAssembly

How Ελιωτος is enhancing WebAssembly security through lattice-based cryptography and quantum-safe execution.

1. WebAssembly and Quantum Threats

WebAssembly's sandboxing capabilities are robust, but as quantum computing progresses, traditional authentication mechanisms in runtimes become vulnerable. Ελιωτος is addressing this by integrating quantum-resistant algorithms directly into our WebAssembly execution pipeline.

Code Example: Quantum-Secure Module Loader

const pqCrypto = async () => import('./pq-loader.wasm');
const loader = await pqCrypto();
const secureHash = loader.generateKyberHash('webassembly-runtime');
console.log(`Quantum-resistant hash: ${secureHash}`);
                

2. Runtime Security Enhancements

Zero-Trust Sandboxing

Each WebAssembly module execution is verified with post-quantum signatures before instantiation.

Memory Obfuscation

Quantum-safe XOR masks applied to memory regions to prevent cold boot and side-channel attacks.

3. Performance Impact

4.8ms

Hash generation time

1.2MB

Security module overhead

2.3x

Throughput improvement

4. Integration Strategy

Our approach includes runtime patching of WebAssembly modules with quantum-safe wrappers, continuous monitoring of cryptographic advancements, and participation in W3C WebAssembly Security Working Group discussions. We're also optimizing lattice-based algorithms for embedded WebAssembly environments.
